Re: [Gimp-developer] GEGL Gaussian Blur (Gimp/gegl git)

Victor must have done some magic since he sent me an email saying that he
was looking into the OpenCL bug. I can now say that this is gone and in
fact GEGL is considerably more stable. I can actually work on 16-bit tiffs
without crashing! :)

I was so excited about this that I rebuilt both Windows and Mac and posted
on my website.

Thanks devs!

Further information to my post. I built on Windows 7 64-bit and here I
have 16G of RAM with dedicated Nvidia graphics. It crashes my video driver

I am finding that one possible show stopper is the gegl gaussian blur.

Here is a simple example. Open a 16bit, say 12 MP tiff image. Duplicate
Layer, and run gegl gaussian blur with x=y=100. On my Macbook Pro with 8G
RAM, either I will get vertical lines on the layer (at best) or crash my

Is there a way to speed up gaussian blur or is this a Mac issue and never
happens on Linux?
